A baseball hit with a bat accelerates more than a bowling ball hit with a bat.
What is Newton's 2nd law?
100
This force opposes the force of gravity when objects fall through the air.
What is air resistance?
100
These types of forces cause changes in motion.
What are unbalanced forces?
100
This is another name for Newton's 1st law.
What is law of inertia?
100
Mass in motion is also known as this?
What is momentum?
200
A balloon flies forward when air quickly escapes it.
What is Newton's 3rd law?
200
These are the two factors that affect gravity.
What are mass and distance?

Mikaia pushes a box with a force of 10 N to the right and Lisa pushes with a force of 3 N to the left. This is the net force applied to the box.
What is 7 N to the right?
200
The more you have, the more inertia you will have
What is mass?
200
If the mass of a bulldozer is 1,250 kg and it is moving at a speed of 20 m/s, this is much momentum does it has?
What is 25,000 kg*m/s?
300
A book left on the table overnight is there when you return in the morning.
What is Newton's 1st law?
300
This is the acceleration due to gravity on Earth.
What is 9.8m/s2?
300
This is the unit of weight.
What is Newtons?
300
This law that states that an object accelerates in the same direction as the force applied.
What is Newton's 2nd law?
300
This force best explains why a feather does not fall at 9.8 m/s2 like expected.
What is air resistance?
400
You run into a friend while skating and you both fall in opposite directions.
What is Newton's 3rd Law?
400
Ignoring air resistance and friction, this should be observed about two objects that are dropped at the same time.
What is both objects should have the same acceleration?
400
These are 3 common forces that can be applied to objects.
What are
Friction
Gravity
Air resistance?
400
This would be the weight of a 60 kg man.

What is Fast airplane, fast bicyclist, slow bicyclist, parked car?
500
The bike you are riding hits a hole and stops quickly, but you fly forward.
What is Newton's 1st law?
500
The maximum speed a falling human can reach is 55 m/s (or 118.06 mi/hr.) This is the name for this speed and these two forces become balanced for this to be possible.
What are
Terminal velocity

The force exerted on a cart is constant. On a frictionless surface, if the cart’s mass is increased, this will happen to its acceleration. Include which law supports your answer.
What is Decreases, because of Newton’s 2nd Law?
500
A car accelerates from 20 m/s to 60 m/s in 5 s. If the mass of the car is 150 kg, find the force on the car and the final momentum.
